There's a possibility that a standalone encoder might work better than whatever
mythtranscode uses (I don't have much experience with mythtranscode as I edit
and reencode to MPEG-2 to make DVDs).  It's also possible that the AVIs you're
downloading were captured from a cleaner source than whatever is feeding your
PVR-150.
